Key points to remember

Using medicines can double your chances of quitting smoking.¹ They can relieve nicotine craving and withdrawal symptoms.
Getting counseling, along with using medicine, can increase your chances of quitting even more.
If you smoke fewer than 10 cigarettes a day, you may not need medicines to help you quit smoking.
It's rare for someone to get addicted to nicotine medicines, because the nicotine is released slowly into your bloodstream.
The side effects of nicotine replacement products depend on the type of product. For example, a patch can make your skin red and itchy. Medicines in pill form can cause nausea, dry mouth, and trouble sleeping. For most people, the side effects aren't bad enough to make them stop using the medicines.
Nicotine medicines have less nicotine than cigarettes. And by itself, nicotine is not nearly as harmful as smoking. The tars, carbon monoxide, and other toxic chemicals in tobacco cause the harmful effects.
Many insurance companies will pay for all or part of the cost of medicines used to quit smoking.

FAQs

What are the medicines?

Your doctor may prescribe varenicline (Chantix) or bupropion (Zyban) to help you cope with cravings for tobacco. These medicines are pills that don't contain nicotine. You also can use nicotine replacement products, which do contain nicotine.

Medicines that don't have nicotine

Varenicline (Chantix) blocks the effects of nicotine and reduces cravings and withdrawal symptoms. If you start smoking again while you are taking the medicine, you won't feel as satisfied. This improves your chances of quitting. You start taking the medicine about a week before you quit smoking, and you take it for 12 to 24 weeks. You take it 2 times a day, after meals.
Bupropion SR (Zyban) can help balance chemicals in your brain to reduce your withdrawal symptoms. Doctors also prescribe this medicine (under the brand name Wellbutrin) to treat depression. But it can help you stop smoking even if you don't have depression. You start taking bupropion daily about 1 to 2 weeks before you quit smoking. This builds up the level of medicine in your body. You keep taking it for 7 to 12 weeks after you stop smoking.
Nortriptyline (Aventyl, Pamelor) and clonidine (Catapres) may be prescribed if the other medicines don't work or you can't take them.

Nicotine replacement products

Nicotine replacement gives your body some nicotine to help reduce withdrawal symptoms and cravings. Nicotine is addictive. But this treatment has about one-third to one-half the amount of nicotine in most cigarettes. It also delivers the nicotine slowly, so it's not as addicting as the nicotine in cigarettes. And these products don't have the harmful tars, carbon monoxide, and other toxic chemicals that are in tobacco.

There are several types of nicotine replacement:

Gum and lozenges slowly release nicotine into your mouth.
Patches stick to your skin and slowly release nicotine into your bloodstream.
An inhaler has a holder that contains nicotine. It delivers a puff of nicotine vapor into your mouth and throat.

You can buy nicotine gum, patches, and lozenges without a prescription. You need a prescription to buy inhalers. You may be able to use a couple of these products at the same time, such as a patch and gum. But talk to your doctor first to make sure it's okay to mix nicotine medicines. People younger than age 18 can't buy the over-the-counter products, but a doctor may prescribe them.

Talk to your doctor if you're pregnant or planning to become pregnant and want to stop smoking. Most doctors will recommend that you try other ways to stop smoking before using nicotine replacement.

Be sure to talk your doctor before using these products if you have a health condition, such as mental illness or heart problems.

How well do medicines work?

Medicines can double your chances of quitting.¹

Some studies have found that varenicline (Chantix) works better than bupropion SR (Zyban).² But every person is different, so one medicine may work better for you than the other.
All forms of nicotine replacement products work about equally well when used in the right way.³
Your chances of quitting smoking are even better if you combine medicines with other help, such as counseling.¹

What are the risks of using medicine to quit smoking?

Medicines that don't have nicotine

The most common side effects of varenicline (Chantix) include:

Nausea.
Increased dreaming.
Insomnia.

Some people also have side effects such as nausea, headaches, and dizziness.

Varenicline may cause some mental illness symptoms, such as depression. Be sure to talk your doctor before using these products if you have a mental illness.

Some people who take bupropion SR (Zyban) have:

Dry mouth.
Trouble sleeping.

There is a small risk of having seizures when you use bupropion. The risk increases if you have had a head injury or seizures.

Tell your doctor about all the medicines you take. When you stop smoking, there may be a change in how other medicines work for you.

Nicotine replacement products

The side effects depend on the type of nicotine replacement product.

Nicotine patches can cause itching and redness where you put the patch. If you use a 24-hour patch, you may have trouble sleeping or have very vivid dreams. This is because your brain isn't used to getting nicotine when you're sleeping. Taking off the patch after 8 p.m. may help ease your sleep problems.
Nicotine gum can cause an upset stomach (nausea) or heartburn. Gum is not a good choice for people who have dentures or problems with their jaw joint (TM disorders).
Nicotine lozenges can cause an upset stomach, hiccups, heartburn, headaches, and gas.
Nicotine inhalers can cause a cough, a scratchy throat, and an upset stomach. An inhaler may not be a good choice if you have asthma, allergies, or a sinus problem.

Why might your doctor recommend that you use medicine?

Your doctor might recommend that you use medicine to stop smoking if:

You have tried on your own to stop smoking, but you weren't able to stop.
You smoke more than 10 cigarettes a day.

Personal stories from people who have quit smoking

These stories are based on information gathered from health professionals and consumers. They may be helpful as you make important health decisions.

"I started smoking when I was in the military. But it is affecting my health, and I want to quit. I've tried the patch, gum, and cold-turkey methods to quit, and they didn't work. So I talked with my doctor about quitting, and he suggested that I try using Chantix. He also recommended that I have counseling and join a support group. It's been a little over a month since I started Chantix, and so far it is helping with my craving to smoke. Talking in counseling is also helpful. I think I finally am going to be able to quit. "

— Dave, age 42

"I thought about taking medicine to quit smoking, but I already take several other medicines for health problems. I just didn't want to take another prescription medicine and take the chance that it might cause problems. So I decided to try the nicotine patch. I set a date and started planning for the physical effects of quitting, like having munchies around and cleaning my car and house. I started with the largest patch available. It was great because the withdrawal symptoms were hardly noticeable. Then I went to the medium patch and finally the smallest patch. Now I don't smoke anymore. "

— Alanna, age 44

"I started smoking at 15. I always thought I could quit at any time and had tried to quit dozens of times. But then I'd start craving a smoke, and I'd go back to cigarettes. A few years ago, my doctor suggested I try taking Zyban. It was great, because the withdrawal symptoms were hardly noticeable. I had to take the pills for 6 months, but they worked. I haven't smoked for 2 years. "

— Carlo, age 52

"My friends pushed me to quit smoking and suggested I talk to my doctor about getting some medicine to help. But I just wasn't comfortable with the idea of taking medicine. I have a strong will, and when I put my mind to doing something, I can usually do it. So I took my doctor's advice to have professional counseling to help improve my chances of success. I quit smoking—cold turkey—5 months ago. All my friends are really surprised that I could quit like that. It has been tough at times fighting the cravings, but it has worked. "

— Kesia, age 35
